qmi-firmware-update in openwrt with all features

[Aleksander Morgado]

Hey!

I've merged in git "main" a branch that enables all the features of
qmi-firmware-update, even in systems without udev, like openwrt. The
MR was: https://gitlab.freedesktop.org/mobile-broadband/libqmi/-/merge_requests/317

This means that in openwrt there is no longer any need to use the
"manual" mode, where it's quite easy to make mistakes.

The "normal" mode allows the user to run the upgrade just providing a
device identification option, plus the images to download, e.g.:

$ sudo qmi-firmware-update -u -w /dev/cdc-wdm0 -p SWIX55C*

setting firmware preference:
  firmware version: '03.04.03.00'

    NOTE: in order to validate which is the firmware running in the
    module, the program will wait for a complete boot; this process
    may take some time and several retries.

firmware update operation finished successfully


The tool will take care of validating the images, requesting the
correct settings to download, waiting for the QDL device, performing
the upgrade, waiting for the device to reboot again and finally check
the version strings reported to see if the upgrade was successful or
not. Users of normal distributions with udev already knew about these
features, but they are totally new to openwrt users.

Please check qmi-firmware-update --help or --help-examples for more
info on how to use it.

Cheers!
